I D/L the 5 for a tial. First, it asked me to remove previous version. I did.
Then it installed ok. After a couple of trials, I wanted to go back to the stable version. The problem comes. When I run the install program, It says detected a MyDAC package (obviously it is the beta 5), and ask to uninstall and run this program again. In the old version, the install program can remove the package , in 5, it can not. So, I mannually uninstall it within Delphi 2006. But things getting worse. no MYDAC component left. I try to reinstall 4.3, but it told me there are some entry point error in dac100.bpl. The old packge can not display in the tool palette. It keep showing 60/60 left for a tial each time when starting Delphi.

What shall I do?

Please tell us if you have any other Core Lab DAC products (ODAC, SDAC, IBDAC) installed in the same IDE.

There was an odac 570 installed before. But I uninstalled that , the problem is still the same.

This version of ODAC is not compatible with MyDAC 5, so this may cause the problem. MyDAC 5 can be installed only with the corresponding build of ODAC 6. To resolve this problem please perform the following steps:
- uninstall MyDAC if it is installed;
- install MyDAC 5 Trial with the /force directive (something like this: mydac10.exe /force);
- uninstall MyDAC 5 using Add and remove programs tool from the Windows control panel;
- install MyDAC 4 once more.

Thanks , problem resolved. I nearly reinstall the Delphi. Four line reply saved me.
